rincon   This document presents the information required by the Colombian environmental regulator as a requirement for a production system that has to do with the thermal treatment of animal by-products, specifically the tallow used for the production of solid soap of the company JABONES EL TIGRE Y LA ROCA S.A.

   For the elaboration of the study, an evaluative research methodology has been used with the purpose of evaluating the effectiveness of the system of control of atmospheric emissions by absorption in water with the scrubber of the company. Initially, the obligations imposed by the national authorities are identified through the regulations defined by the Ministry of the Environment and Sustainable Development.

sauco   The generation of odours in a WWTP is usually caused by the presence of hydrogen sulphide (H2S). This gas, moreover, is responsible for the deterioration of the facilities’ materials and involves a health hazard for plant operators. Currently there are several alternatives that allow decreasing the impact of odours associated with H2S.

   This paper presents some techniques focused on management of odours in WWTPs as a result of the experience of DAM as WWTP Manager: experiences of removal of H2S in collectors, deodorization of a WWTP by the injection of confined air in the anoxic biological reactor of the sludge line, studies at pilot scale for the application of a TECNIUM’s biofilter percolator, a photo-ionization for the treatment of air streams, and ozone plus ultrasound for the treatment of liquid streams.

GAroca   The processing of meat by-products for the production of protein meals entails the generation of gaseous emissions causing annoying odours that cause a severe environmental impact in the surrounding populations.

   This work presents the characterization of the main components of the process emissions, the dimensioning of the treatment system and the results of the operation of a rendering plant of turkeys, where fractions, such as viscera, blood, feathers, as well as seizures and discards, are processed to produce flour and oil for animal feed. This plant has a processing capacity of 8 million turkeys per year and a projection of 12 million.
